TalkEdit

This page says that Neodymium-145 is stable, but both Isotope table (divided) and Isotope table (complete) say that that isotope is radioactive. —The preceding unsigned comment was added by 202.89.32.154 (talkcontribs).

Fixed those, as per the references here. Thanks for pointing it out. Femto 14:02, 5 April 2007 (UTC)
